When do you prefer frames instead of windows?

When do you prefer frames instead of windows?

[Raffaele Ricciardi]

The usefulness of frames is evident for buffers that update their 
content according to the current buffer (like Speedbar and ECB). 
Besides this kind of use, when do you prefer frames instead of windows?

Thank you.

Personally, almost always.  A window-manager window (Emacs frame)
is more flexible than an Emacs window - more features/possibilities.

Emacs windows were conceived long, long ago - before window
managers were supported/recognized by Emacs and even, for the
most part, before they existed.  They are vestigial organs that
have some limited uses but are generally not the best way to
interact, IMO.

I generally don't like apps to try to lock everything they do into
a single window-mgr window (frame) and provide their own internal
windows within that frame.  That applies to Emacs also.  Whenever
possible/practical, I free such internal windows to become normal
window-mgr windows.  With Emacs this is even better, as you can
manipulate frames using the keyboard, not just the mouse.

However, out of the box, support for using Emacs frames is pretty
primitive.  So I jump through a bunch of configuration hooks to
be able to use them easily (including keyboard manipulation).

Just one (minority) opinion.

I would ask an opposite question: IF you could use Emacs frames
as easily as you can use Emacs windows, in what scenarios would
you prefer using Emacs windows, and why?

My favourite use of windows is for mail reading, sql interaction
and when working on two parts of the same file or two files with
a macro.

For e-mail, I think you all know at least one between rmail, gnus and
vm.

For sql interaction a sql editing buffer and a db connection buffer
are really a nice way to shot queries to a db for test and debug
purposes.

In these situations I feel that Emacs is "running an application" and
I feel more comfortable with all the application windows in the same
frame.

If the frames could really be used like windows, then, it could be
that I would be comfortable with separate frames.

On the other hand, my favourite use of frames is on an application
specific basis.

One frame for e-mail, one for DB-interaction... Some version ago Emacs
had a nice bug/feature that allowed you to create several WindowMaker
application icons with a single Emacs instance, and using a different
image for each application icon.

This was nice because that let me associate a certain frame with a
certain workspace (i.e. e-mail on workspace 1 and db-interaction on
workspace 6) and use a click on the application icon to jump to that
workspace.

[Now I can just assign different images to different miniwindows.]

That was the question.  "IF you could use frames as easily as you
can use Emacs windows..."  I certainly agree that currently you
cannot, especially with just vanilla Emacs.  But if you could...

That sounds like something that would pertain only to certain
platforms, since different platforms have different notions of
"icon" etc.  But the ability you mention sounds like it might
be useful.

FYI, you can use bookmarks to similar effect.  With Bookmark+ you
can just jump to this or that desktop bookmark, to change between
Emacs "workspaces", as defined by desktop.el.  And it doesn't
matter whether you use one frame or 37 frames for such a workspace.

Frankly, the answer is "I can't answer until I see it working".
But it could be yes, especially if it changes my habits only slightly.

I will give it a look, thank you!

For supporting tasks only: Imagine you are starting from a full-screen
window and want to see temporarily a variable definition in a second
window while still hacking away.  The advantage is that window
operations, like C-x } enlarge-window-horizontally,
delete-other-windows-vertically,... operate simultaneously on all
windows.  In such situations it seems to me much more convenient to use
windows than set it up with frames.

Again - but what "IF you could use Emacs frames as easily as you
can use Emacs windows"?  That's the question.

Pop up a *Help* frame instead of a *Help* window to show help.  Hit
`C-x 0' to get rid of that frame when you're done.  You probably do
not need to resize the frame (e.g., if the frame is automatically
fit to the size of just the *Help* text).  But if you do, then use
keys to resize it, just as you would for a window.

IOW, think past what you can do with a window (resize, move, control
where it pops up, etc.) that you think you cannot easily do with a
frame now.

I certainly agree that if frames are not made as convenient to
interact with (i.e., the same kinds of operations you use on
windows) then Emacs windows remain useful.  But if Emacs *did*
support such operations with frames, out of the box,...

Be very careful with the phrase "use ... as easily as you can use ...".  
There are some people out there who consider pointing with the mouse 
easy.  I, on the other hand find it easier to use the keyboard.  The 
keyboard, along with Emacs' wide array of cursor positioning commands, 
gives me the ability to quickly and easily get to specific precise 
positions - at least precise based on character position in a character 
cell terminal or editor window.

There are probably other areas where different Emacs users would have 
diametrically opposite views on what they consider to be easy.

Yes, but typing C-x o is something I can do easily because it involves 
two fingers on the left hand immediately followed by one finger on the 
right hand, without fingers my ever having to leave home position.  C-x 
5 o, on the other hand involves my typing two successive characters with 
my left hand before I can switch to the right hand for the "o".  And, 
worse than that, "x" is in the bottom row but "5" is in the top row, 
which means that even though my fingers' average position is over home 
position, they're jumping Saturday as far as they ever do on vertically.

All this means that my mental focus on the code I'm writing doesn't get 
distracted when I type C-x 0, but when I type C-x 5 o, I have to take 
some of my focus away from the code to make sure I don't miss the "5" 
after the "x".

As easily as you can using whatever way you currently interact
with windows - keyboard, mouse, foot pedals,...

And I made it clear that being able to use only the keyboard
(if a user prefers that) is required.  That's definitely part
of being able to use windows easily and would need to be part
of being able to use frames easily.  I thought I was clear
about this.

Emacs accommodates them all, now, for windows.  It would be
good for it to do likewise for frames too.  That's the point.

Here you presuppose existing Emacs bindings. Which, as already known,
do not satisfy the “as easily as” criterion.

On the other hand, consider the windmove and framemove packages.
windmove gives you easy bindings, by default Shift+arrows[1], that
switch to an adjacent window in the given direction. Then, framemove
hooks into that and when you don’t have an adjacent window in the
indicated direction, it switches to an adjacent frame in that
direction.

[1]: if you use cua-mode, it makes sense to rebind windmove to e.g. Alt+arrows.

For those of you who find keyboards easier than mice to use have you 
ever tried using a track bal and if so how do you grade that in 
comparison to use of the mouse?

In the old Windows (95, 98, 2000 - after that I gave up with Windows)
there were also the options to have in e.g. the Turbo Pascal IDE the
windows in one application window (as "windows" under emacs) or as
separate windows (as frames under emacs). And everybody had different
preferences. And I think it it the same here.

One major advantage under Linux when using frames instead of windows, is
"focus follows mouse" - you can simply switch between different emacs
frames by moving the mouse, which you can't when using windows. I know -
I take cover - real emacs user don't use the mose, but for me it was
faster to move the mouse then switching to a different frame, especially
when more then one frame was present.

Now I am using a Mac - not because I don not like Linux anymore, but
because I think the hardware is simply brilliant - with OSX (Linux does
not play nicely along with the retina display and the touch pad the last
time I teried it out) the focus does not follow the mouse, so I am using
frames as kind of topical separation for my buffers.

One other advantage of using frames is multiple monitors - one frame per
monitor.

Rainer

Re: When do you prefer frames instead of windows?

I use M-x compare-windows a LOT.  So, I'll usually have at least one 
frame big enough to hold two side-by-side 80 column windows, and that's 
where I'll do most of my work.  However I tend to open a new frame for 
things where I want to see an additional file briefly.

Also, I'm frequently running a local terminal emulator, and from that 
emulator's shell prompt I've got an ssh connection to a remote host on 
which I'm running emacs.  Under those circumstances, frames are not an 
option, so I use emacs windows for everything.

Thanks for the reminder.  That is one of the few cases where I do split
a frame into windows. Only because `compare-windows' (unlike Ediff, for
example) does not work across frames.  I should probably code up an
enhancement for it that does, but I don't use `compare-windows' that
often anymore, for some reason.

To preserve sane window layouts despite a multitude of major modes.

For example: Barry Margolin pointed out that he prefers 4 ansi terminals
in a "shell frame".  I like to have a "file manager" frame with two
dired buffers side by side. Gnus literally "demands" his own frame in
its default mode of operation!

Here's an illustration of my frame setup which is based on Alan
Mackenzie work, so that I'm able to open frames with predefined window
layouts according to various tasks or - if a task frame already exists,
just switch to it.

That wasn't me, it was someone replying to my post.

I just said I use one frame because it's an old habit. I've been using 
Emacs since 1980, multiple frames weren't added until 1994.

Another advantage of windows over frames is they work the same whether 
you're using Emacs in a GUI or terminal. Although I admit that when I 
need to do a quick edit in a terminal, I usually use vi. This is usually 
when I'm ssh'ed into a server, and they usually don't have Emacs 
installed, and even if they did I wouldn't have all my extensions there.

If I have two distinct tasks that each require a set of buffers then
sometimes I create two frames.

As others have mentioned there are advantages to using frames.  Modern X
Windows environments have keybindings for common operations on frames.
However, Microsoft Windows only has a few of those, to tiresome
switching between the keyboard and mouse is needed.  I use both X and MS
Windows daily.  I generally prefer using Emacs windows rather than frames
becuase they can be manipulated using the keyboard on all platforms.

It should be possible, out of the box, to do that in Emacs itself.
One set of keys for all platforms, and any set of keys you yourself
choose.

You need to be able to do the same kinds of things with frames
that you can do with Emacs windows - *from the keyboard* (and with
a mouse). Including move around incrementally, resize incrementally,
cycle/choose, tile/split, and so on.

I use Emacs that way, but as I say, this is not provided out of the
box with `emacs -Q'.  (It should be, IMO.)

I really would be interested in people's answers to my question, BTW:

You are throwing teaser around - is your emacs config some=where on=ine,
so that I could take a look at your configuration regarding frames?

I really did not mean it that way.  I'm more interested here in
looking at the use cases that people might think really apply to
Emacs windows inherently.

It's about a thought experiment: WHAT IF you could easily do with
frames what you do with windows, using the keyboard (or the mouse)?
Would you still see some scenarios where you would prefer to use
a window?  If so, what would they be?

I do use code that tries to make frames more convenient to use, but
that really is beside the point of my question.  What I would like
is for vanilla Emacs to provide frame-friendly manipulation.

I do understand that Emacs does not have real control over
window-manager windows (i.e., frames); it can only request/suggest
changes to be made by the window manager.  And different platforms
& window managers are different, so it is likely that there would
never be a 100% cross-platform solution with the level of control
that we have with Emacs windows.

Still, I know from my own experience that it is possible to obtain
pretty much all of the control I expect, at least across GNU/Linux,
UNIX, and MS Windows - I can't vouch for others.


[If you do want to try the code I use, just to get an idea of what
I mean, look here: http://www.emacswiki.org/OneOnOneEmacs.
But again, I'm *not* proposing such code as the solution or even
as *a* solution to the problem of easily doing with frames what
you do with Emacs windows.  This is code that I use to try to
overcome the problem, imperfectly.  That's all.]

At my job, I have a dual monitor setup (16:9 24" + 4:3 20"). I split
my left monitor into two window stacks with i3wm, then put an Emacs
frame in each stack. This gives me roughly 100-character-wide frames
which happily coincides with my team’s coding standard.

This way, I can work with up to 4 buffers when necessary, or
independently switch any of the stacks to a different application
(xterm or Firefox or whatever).

Single frame for Ediff: A on top, B in the middle, Control at bottom.
The separate control frame is a nuisance with focus-follows-mouse, it

Seems like that is something that could be fixed.  Have you
thought about filing a bug report / enhancement request?
(`M-x report-emacs-bug')

FWIW, I've been using Ediff with separate frames for decades,
and I don't have any such problem.  But I don't use
`focus-follows-mouse'.

In principle, Ediff should play well with separate frames.

It's not a bug... :-) I don't think there is anything that emacs can do
about it.  If I want focus-follows-mouse (and I want it :-), then moving
the mouse out of the ediff control frame really should move the mouse
out of it, and not try to be helpful and force the mouse inside the
control frame or such nonsense.

I now have bound a key to get my ediff control panel back:
    <C-M-up> runs the command (lambda nil (interactive) (let ((buf
    (get-buffer "*Ediff Control Panel*"))) (if buf (pop-to-buffer buf)))),
    which is an interactive Lisp function.
and then C-l recenters everything (could even pack that in the
keybinding, but...)

Is that not what happens?  I would think that that is a bug.
I agree that with focus-follow-mouse the focus should follow
the mouse. ;-)

And if it did do that?  What would the problem be with Ediff, in that
case?  I should think that there would be no problem.

If you leave your mouse in the Ediff Control Panel frame then focus
should stay there, and if you move it out of that frame, into another
frame, then focus should leave that frame.  That should be no different
from turning off focus-follows-mouse and clicking in a frame to focus
it.

Assuming that this worked (if it does not), what would the problem be
for Ediff, for your use?

I don't think Ediff should be grabbing focus back, if you have
asked that focus move elsewhere (which you do when you move the
mouse out of the control frame).  This sounds like a bug, to me (FWIW).

Agreed, and that is exactly what happens.  No fault of emacs anywhere in

During an Ediff Session, sometimes I have to leave the Control Panel to
check something in a different window or buffer, or even on a different
desktop.  When I get back to Ediff: where is my Control Panel?  Yes, of
course it is still where I left it, upper right corner of the screen,
but obscured now by the terminal, firefox or any other odd window I
happened to raise over it during my check-something-outside-of-ediff.
And even if the Control Panel is still visible on the screen, the mouse
is no longer inside that Control Panel.

In order to get my ediff session back, I have to accurately raise the
control panel, raise emacs (I *think* they are connected somehow, so
maybe this is not necessary), place mouse accurately inside (tiny)
Control Panel, pay attention not to nudge it out of there etc etc.

Compare to single frame ediff: move mouse anywhere into (large) emacs
window, press C-M-Up, press C-L, continue with ediff.

And no, I will *not* enter a bug report for this, even if it were one ;-)

Yes, this is why Emacs should provide simple key sequences to raise
and refocus frames.

It's no different from what happens if you (one way or another)
select another window, if that window obscures (e.g. replaces) the
window you previously had selected.  You need an easy way to select
arbitrary windows and frames, including from the keyboard.

Wrt frames obscuring/overlapping other frames (for which the window
analogy is windows replacing other windows, or windows simply being
removed), it helps a lot if you let frames be automatically fit to
the size of their displayed text (within max & min limits you set).

Yup.  A PITA.

Yes.

Consider binding a key to refocus the Ediff Control Panel frame.
You can bind it for just the duration of the Ediff command.  (The
function to raise and focus a frame is `select-frame-set-input-focus'.)

Raise-frame and lower-frame can be easily bound to whatever keys you like. 
Other-frame is already bound by default to C-x 5 0
It can't get much easier than that.
There's a host of functions for frame management, try C-h a frame for many more

Of course.

> It can't get much easier than that.

Yes, it can.  If you have 30 frames then you don't want to cycle
through them to get to the frame you want.  Same problem with
windows and `C-x o', but there you are limited to the windows
in a single frame (by default), and it is less likely that you
will have 30 of them, or even 10.

Cycling through lots of candidates, even given the additional
(prefix-arg) possibility of specifying how many to go forward
or back, is a pretty rudimentary UI when there are many candidates.

It can definitely get easier than that.  One possibility is to
let you (i.e., optionally) choose a window/frame by name, with
completion.

> There's a host of functions for frame management, try C-h a
> frame for many more

Still not good enough, IMHO.  There is lots of room for
improving how Emacs plays with frames.

FWIW, this is what I bind to `C-x o':

,----
| C-x o runs the command icicle-other-window-or-frame, which is an
| interactive compiled Lisp function in `icicles-cmd1.el'.
| 
| It is bound to C-x o.
| 
| (icicle-other-window-or-frame ARG)
| 
| Select a window or frame, by name or by order.
| This command combines Emacs commands `other-window' and `other-frame',
| together with Icicles commands `icicle-select-window',
| `icicle-select-frame', and `icicle-choose-window-for-buffer-display'.
| Use the prefix argument to choose the behavior, as follows:
| 
|  With no prefix arg or a non-zero numeric prefix arg:
|   If the selected frame has multiple windows, then this is
|   `other-window'.  Otherwise, it is `other-frame'.
| 
|  With a zero prefix arg (e.g. `C-0'):
|   If the selected frame has multiple windows, then this is
|   `icicle-select-window' with windows in the frame as candidates.
|   Otherwise (single-window frame), this is `icicle-select-frame'.
| 
|  With plain `C-u':
|   If the selected frame has multiple windows, then this is
|   `icicle-select-window' with windows from all visible frames as
|   candidates.  Otherwise, this is `icicle-select-frame'.
| 
|  With plain `C-u C-u':
|   Same as `icicle-select-window' with a negative prefix arg: Select a
|   window from any frame, including iconified and invisible frames.
|   
|  With plain `C-u C-u C-u':
|   This is `icicle-choose-window-for-buffer-display', with windows from
|   all frames (i.e., iconified and invisible) frames as candidates. 
| 
| If you use library `oneonone.el' with a standalone minibuffer frame,
| and if option `1on1-remap-other-frame-command-flag' is non-nil, then
| frame selection can include the standalone minibuffer frame.
| 
| By default, Icicle mode remaps all key sequences that are normally

`C-x 5 0` is bound to `delete-frame`. `other-frame` is bound to `C-x 5

Compare with frames: C-x 5 o to cycle through the frames until you're back to the control panel(1-n times depending on how many other frames you have).  Works way better than trying to raise/lower/etc.

You might want to go further (I know I do!) and make bindings that (1)
temporarily switch to the ediff control panel, (2) perform an ediff
control panel command, (3) switch back to the buffer you were in — for
each command that you frequently use in ediff. (Personally I find

Yes, they came about on ASCII terminals, long before graphical 
interfaces became common.

Since I've been using Emacs since those days, I long got used to using a 
single frame with Emacs windows in it. Now, even though I use it on a 
Mac with a wide screen, I still can't get into the habit of using 
multiple frames.

Re: When do you prefer frames instead of windows?

[Jai Dayal]

I just use them when I like having different window arrangements based on
content. For example, I like my code buffers split one way, but for
actually running the application's workflow, I like having a window with 4
different ansi-terms split in quarters. Being able to switch easily between
the different frames makes it very easy.

The one thing I like about Emacs windows as opposed to frames is that
they resize automatically: when you create one, another window is
reduced in size, so that the new window doesn't cover it, and when you
delete one, another one grows in order to occupy the space that becomes
available.

I tend to work in a single window occupying a maximised frame, and when
I want/need to do something else, I usually switch to that buffer. (I'm
perfectly happy letting mu4e or ebib or ediff or whatever take over the
entire window, hiding what I was working on before.) When I do split the
one window, it's usually for something I only need to take a quick look
at (help buffer, error messages, etc.) I don't want that window to cover
what is in my "main" window, and I want to get rid of the extra window
as soon as I'm done with it.

AFAIK this automatic resizing isn't possible or at least not as easy
with frames. I find this a definite advantage of windows over frames,
and to be honest, I don't see what advantages frames have over windows.
(You mention they have more features/possibilities, but I'm not sure
which features you mean...)

Agreed, but in a way you are making a virtue of necessity.  From
the moment that the design is such that windows cannot overlap,
they *must* be resized, repositioned within the frame, or replaced
by another window, as the only possible adjustments for visibility.

Frames can overlap.  That is a strength, not a weakness.  It is
an additional possibility, but they need not overlap.

Nothing prevents a set of frames from having the same limited
behavior that you like in Emacs windows: tiling, replacing each
other, resizing relative to others shown, etc.  In addition
or alternatively, frames can overlap each other (by default).

Are there advantages to overlapping and arbitrary (pixel-level)
positioning?  I think so.  The analog to overlapping, for windows,
is to turn on line truncation and allow an adjacent window more
space.  IOW, when you want to see more of one and are willing to
forego seeing some of the other (but still see some of it), that's
what you do with windows.  (For the vertical case, just resize.)

It is possible.  It is not provided (so no, it is not as easy).

Agreed.

Whatever can be done with windows could be done with frames,
AFAICT.  That all of that is not easily available is another
story.

In addition, frames can be positioned arbitrarily.  They are
not constrained to be within anything, other than your display.
And positioning is at the pixel level.  That's about it, AFAIK.

There are some other frame parameters that might not have
analogs for  windows (can't think of them, offhand), but
essentially it's about arbitrary positioning.

(There is also iconifying, but whether you look at that as a
useful feature is up to you.)

I have seen a lot of commentary about frames.  One thing that has been
missing is the discussion of the window manager used to manage those
frames.  It really isn't possible to talk about emacs and frame
management without also involving the window manager.  "Ay, there's
the rub."  And that is as personal of a choice as the choice of
editor.  Focus follows mouse?  Click to focus?  Click to raise?
Autoraise?  Tiling?  Single or multiple screens?  The combination of
possibilities will create a large number of answers.  None of which is
canonically correct.  All are correct for that individual.

Personally I tend to use one frame for everything.  I sometimes use
additional frames but only rarely.

Of course.  But Emacs does provide basic operations for manipulating
frames, and they work across platforms, and they already take into
account user choices (focus follows mouse etc.).

What is missing out of the box, IMO are:

* Better UI - commands and bindings, to do things that we
  currently do with windows.
* Better interaction between the rest of Emacs and frames.

The second one is harder to fix in one sense: doing so probably
will involve fixes across different platforms.

But the main obstacle, IMO, is that few people use frames a lot,
and with fewer users there is not the necessary consideration
of cross-functional behavior (e.g. how this or that feature
plays well with frames).  Emacs developers, like most Emacs users,
do not pay as much attention to the case of using frames instead
of windows.  Less attention when it comes to design and
implementation, and less attention when it comes to updates & bugs.

That's just the way it is, and it's normal: more attention
goes to what more people use more often.

The main reason why I don't use frames is because the window manager on
OS X lacks too many features (in particular regarding multiple desktops
and keyboard navigation). So I use a single emacs frame in full screen
mode, and workgroups2 to manage several groups of windows (this is quite
useful for modes that enjoy destroying carefully arranged windows, yes
gnus I'm looking at you).

I was using multiple (full screen) frames instead of workgroups at some
point, but I stopped because ERC notifications would not be aware of the
frame being visible or not, so I would get no notification at all. Also,
the possibility of restoring frames using desktop.el was not available
then (I think it's new in emacs 24.4).

This. Workgroups is an outstanding extension. It seems to me that, for all
the presumed uses of frames for managing multiple groups of windows,
workgroups can do it better, providing out of the box most of what this
thread is seeking from frames.

OK, that's one point.

But that's a different point.

I'm not familiar with workgroups2, but "managing multiple groups
of [Emacs] windows" is not "most of what this thread is seeking
from frames."

IOW, so far, it sounds like workgroups2 might be an argument
*not* to use Emacs windows instead of frames.  But so far, it
does not sound like an argument for using workgroups2 (or
using Emacs windows) instead of frames.

I always have 10's of frames open when coding, so I can easily switch 
between them, while each is a full window.

I use windows a lot in conjunction with keyboard macros.  The macro will 
do something in one window, switch to the other window to do something 
else, then back.

E.g., converting a big case statement <-> macro #defines, making 
function prototypes from functions, any repetitive multi-file macro.

    I use a new frame only when I want it on a different workspace.

    I use a second (or, occasionally, a third) window when I need to
    refer to one buffer while working in another (e.g.
    http://t.cfaj.ca/emacs-cv.jpg).

    Other than that, I use multiple buffers, often having as many as
    50 open at once.

bounds-of-thing-at-point for paragraphs

That is very nice.

I like ivy-mode from GNU ELPA, it is package for automatic completion
of many functions. There are many various completion packages.

It may help you faster explore which functions are available.

I was looking if such function already exists by doing {C-h f} and
then I get list of functions, I have tried typing "trans" and "para"
and I can find function `transpose-paragraphs'

You may spare your efforts by finding some probably already existing
functions.

If you wish to make your own function out of `transpose-paragraphs'
you may come with cursor on the function name, above here ^ and type
{C-h f} then you press TAB and enter into file `paragraphs.el' where
you can find how function is written.

Then you may copy the same function and name it
`my-transpose-paragraphs' and try modifying it as you wish. You could
as well modify original function to do what you wish and save it in
your configuration.

See below:

> (defun Skip-Over-Paragraphs (arg)

I understand that some programming languages have mixture of upper
case and lower case function names, in Lisp that is not so common. I
believe it is common in some versions of Lisp, not in Emacs
lisp.

As:

(setq A 1)
(setq a 2)

are not same so, so it is better writing all lower case letters.

I understand you may need now for visibility or orientation some space
at ( (Beg)) yet by convention there is no such space. You better not
make new lines after let* to make it easier readable for people who
are familiar to different style. Lisp is great, you may write it
anyhow, but for readability there are some conventions.

You may mark the function and simply press TAB and it will indent it
for you.

Please see the Emacs Lisp manual as it is built into Emacs. There is
section "Tips" where you can read various conventions.

Normally ending parenthesis you put straight after t.

I suggest you use Options -> Highlight matching parenthesis to help
you see where you are.

Yes, but transpose-paragraph does not keep at the same point position.

I was asking how bounds-of-thing-at-point does not take paragraph as argument
as well, since it does for word, sentence, line. Can paragraph be included as well?

But it does.

(bound-of-thing-at-point 'paragraph) works fine.

(thing-at-point 'paragraph) also works fine.

See (emacs) `Paragraphs' for info about how paragraphs
are defined for Emacs use.

It works fine, but documentation does not describe it:

bounds-of-thing-at-point is an autoloaded compiled Lisp function in
‘thingatpt.el’.

(bounds-of-thing-at-point THING)

Determine the start and end buffer locations for the THING at point.
THING should be a symbol specifying a type of syntactic entity.
Possibilities include ‘symbol’, ‘list’, ‘sexp’, ‘defun’,
‘filename’, ‘url’, ‘email’, ‘uuid’, ‘word’, ‘sentence’, ‘whitespace’,
‘line’, and ‘page’.

See the file ‘thingatpt.el’ for documentation on how to define a
valid THING.

Return a cons cell (START . END) giving the start and end
positions of the thing found.

> (thing-at-point 'paragraph) also works fine.

Also there documentation is not describing it:

thing-at-point is an autoloaded compiled Lisp function in
‘thingatpt.el’.

(thing-at-point THING &optional NO-PROPERTIES)

  Probably introduced at or before Emacs version 20.

Return the THING at point.
THING should be a symbol specifying a type of syntactic entity.
Possibilities include ‘symbol’, ‘list’, ‘sexp’, ‘defun’,
‘filename’, ‘url’, ‘email’, ‘uuid’, ‘word’, ‘sentence’, ‘whitespace’,
‘line’, ‘number’, and ‘page’.


Could somebody update documentation for those functions?

Just read it more carefully.

1. "Possibilities include"
                  ^^^^^^^

   It doesn't say that those are the only possibilities.

2. It points you to "`thingatpt.el' for documentation on
   how to define a valid THING."  IOW, for documentation
   what makes a THING defined for use by `thing-at-point'.

See above.  The word "include" doesn't mean the
same thing as "include only" or "comprise".  The
list of THINGS mentioned isn't exhaustive.

The English language includes the words "thing"
and "point" (but it also includes a lot more words).

Re: RE: bounds-of-thing-at-point for paragraphs

[Christopher Dimech]

Looking at thingatpt.el is not helpful.  If you know important things
that are useful to know about it, place it at the top of the file.

I customarily define a documentation function for the file so that it
would be available interactively, even if mostly of interest to Elisp
Designers.

It's very helpful.  It directly answers your question.

Or perhaps you meant that needing to look at that file
is a burden.  That's different from saying that if you
do look in the file you find no help.

> If you know important things that are useful to know

Define "top" of the file.  Elisp files have certain
things, conventionally, at the very top.

One of the things they can have near the top, i.e.,
in the file header, is a Commentary section, which is
documentation.

And lo and behold, what do we find there, in lines
4-7 of the Commentary?  

 The function bounds-of-thing-at-point finds the beginning and end
 positions by moving first forward to the end of the "thing", and then
 backwards to the beginning.  By default, it uses the corresponding
 forward-"thing" operator (eg. forward-word, forward-line).

That directly answers your question, no?

What happens when you do `C-h f forward- TAB'?  Do you
see `forward-paragraph' listed?  QED.

You want interactive access to just the Commentary?
Your wish is granted:

 M-x finder-commentary thingatpt

That's how I got the text to include in my answer to
you, without having to remove comment chars (`;').

(And yes, you can use `TAB' with `finder-commentary'
to see all of the currently available libraries as
candidates.)

Nope, not what I meant.  Sure, you can bring up

Of course I brought up the whole file.  Yet I could not figure out
about the paragraph thing.  Which region are you referring that is

As a sidenote, I found another bug here.

In the buffer created by M-x finder-commentary it should be possible to
quit using "q", but that keybinding doesn't work.  I'll make a bug
report.

I don't see that.  I'm using Emacs 26.3.

`finder-mode-map' has `q' defined as `finder-exit',
which works fine, for me.  Its doc says:

Exit finder mode.
Delete the window and kill all Finder-related buffers.

I can reproduce this.  In fact, I had been about to submit the same
bug when I saw Robert's note (thanks Robert!)

So, likely regression in 27?  I'm not able to check master sadly.

FWIW, I can also repro this on 26.3 under -Q so I no longer think this
is a regression for 27.

What is it that you can repro on 26.3? What's the recipe?

If I use `emacs -Q' then `q' exits with `finder-exit',
which deletes the window (unless it's alone in its frame).

I think that's what `q' has always done in such a Finder
window (until the regression introduced in Emacs 27).

I retested and now agree this is a regression for Emacs 27.

I was intially confused about the different behaviour when the
*Finder-package* is the only window in the frame.  Retesting under -Q
in 26.3 and 27.1 clearly gives different behavior when the commentary
buffer's window isn't made to occupy the whole frame.

Stephan,

I think this should be pushed to the Emacs 27 branch. Are you convinced?

BTW/FWIW -

My library `finder+.el' enhances Finder mode in minor ways.

In particular, it changes `finder-commentary' so it names
the buffer `*Commentary, <FILE>*, not just `*Finder*', so
you can have any number of such buffers and recognize which

There's nothing to activate.  Just load `finder+.el'
(or a byte-compiled version of it, `finder.elc'):

. Put it in your `load-path', then (require 'finder+).

. Or interactively: `M-x load-library finder+'.

. Or interactively, if not in your `load-path':
  `M-x load-file <.../finder+.el[c]>

This is true of any Elisp library.  That is,
assuming the library has a `provide' you can
`require' it, to load it, assuming it's in your
`load-path'.

What happens if you type the whole file name?

 M-x finder-commentary RET thingatpt.el RET

It should find that source file, if you have it.

Similarly, `M-x find-library thingatpt.el' should
find it.

Do you have source file thingatpt.el?  You should
have it, as part of the GNU Emacs distribution.

Maybe if I say Sesame open the door... :-)

I went into thingatpt.el and I tried searching for "paragraph" and I
cannot find it. This opens plethora of possibilities to jump into
maybe other files and find "paragraph" defined.

Alright, sure. But that does not make it friendly to user to
understand that paragraph is included.

Do you have a word "paragraph" in your thingatpt.el?

AFAIU a thing "foo" gets defined as side effect when a function
`forward-foo' is defined.  Seems actually most "things" are defined that
way.

The number of "things" it can support is unbounded.  How would you

customarily dealt by users. Linguistic structures are an example since many Emacs
users deal with words, sentences, and paragraphs on a daily basis.

More documentation is more useful than less documentation.  We can keep the more
exotic things off the list.  Especially THINGS coming from outer space.

I use this, which is a straightforward definition
from the thingatpt.el Commentary.

(defun icicle-defined-thing-p (thing)
  "Return non-nil if THING is defined as a thing-at-point type.
THING is normally a symbol, but it can also be a string that names a
symbol or a cons whose car is such a string.  This is so that the
function can be used to filter completion candidates."
  (when (consp thing) (setq thing  (car thing)))
  (when (stringp thing) (setq thing  (intern thing)))
  (let ((forward-op    (or (get thing 'forward-op)
                           (intern-soft (format "forward-%s" thing))))
        (beginning-op  (get thing 'beginning-op))
        (end-op        (get thing 'end-op))
        (bounds-fn     (get thing 'bounds-of-thing-at-point))
        (thing-fn      (get thing 'thing-at-point)))
    (or (functionp forward-op)
        (and (functionp beginning-op)  (functionp end-op))
        (functionp bounds-fn)
        (functionp thing-fn))))

(defun icicle-things-alist ()
  "Alist of most thing types currently defined.
Each is a cons (STRING), where STRING names a type of text entity for
which there is a either a corresponding `forward-'thing operation, or
corresponding `beginning-of-'thing and `end-of-'thing operations.  The
list includes the names of the symbols that satisfy
`icicle-defined-thing-p', but with these excluded: `thing', `buffer',
`point'."
  (let ((types  ()))
    (mapatoms
     (lambda (tt)
       (when (icicle-defined-thing-p tt)
         (push (symbol-name tt) types))))

    (dolist (typ  '("thing" "buffer" "point"))
      (setq types (delete typ types)))
    (setq types  (sort types #'string-lessp))
    (mapcar #'list types)))

Remove the mapcar sexp in the latter definition, if you
want just a list, not an alist, of names.  Map `intern'
over the list if you want symbols instead of strings.

`C-h o` can display a dynamically-generated list.
E.g. we do that for `pcase` (to list available patterns) and for generic
functions (to list existing methods).

You can remember the point and restore it.

You could try to define it. There is function org--paragraph-at-point
that gives information about paragraph at point. Try it out.

No need.

From the Commentary of file `thingatpt.el':

;; The function bounds-of-thing-at-point finds the beginning and end
;; positions by moving first forward to the end of the "thing", and then
;; backwards to the beginning.  By default, it uses the corresponding
;; forward-"thing" operator (eg. forward-word, forward-line).
;;
;; Special cases are allowed for using properties associated with the named
;; "thing":
;;
;;   forward-op		Function to call to skip forward over a "thing" (or
;;                      with a negative argument, backward).
;;
;;   beginning-op	Function to call to skip to the beginning of a "thing".
;;   end-op		Function to call to skip to the end of a "thing".
;;
;; Reliance on existing operators means that many `things' can be accessed
;; without further code:  eg.
;;     (thing-at-point 'line)
;;     (thing-at-point 'page)

It's enough that there's a function `forward-paragraph'
that moves forward over a paragraph.

`thing-at-point' is designed to be usable out of the
box with LOTS of things.

There's nothing wrong with it in Emacs Lisp and a number of other Lisp

the dialect that Emacs Lisp is most directly descended from.

Actually, there is in the sense that these are global variables and so

For most other Lisps what the user writes only creates havoc with its
own code because each program runs in its own process.  But Emacs being
its own kind of OS the situation is a bit different.  Of course similar
situations occur with "Lisp machine" kind of systems (or Smalltalk
machines, ...).

Yes.  But, there's still the issue of accidentally creating global
variables.

I think the modern learner will expect "setq" to do what "let"
does unless told otherwise.

"Modern learner"...  Why not just say Lisp learner? ;-)

How/why is "the modern learner" different here from
the learner of 2008, 1998, 1988, or 1978?  (Or `68
or `58, for that matter?)  Am I missing something?

Lexically bound, "ordinary", local variables are as
old as Fortran - nay, assembler.  Nothing particularly
modern about them, or about folks who are used to only
them.  They were even added to Lisp as long ago as the
'70s (at least).

Lisp is typically not a Lisp learner's first language.
Gunk accumulated on eyeballs can need to be scraped

I'm straying off topic here but let me suggest that emacs could (and is) used by first learners and that the Introduction could be used as a Lisp manual for such people.

Hence the need to clarify things and slightly bridge the gap between the Introduction and the Reference.

There is nothing intrinsically difficult to emacs lisp, compared to a language (and ecosystem) like AppleScript that *is* advertised as a first learner language, even though both target the same class of people: users who need to do automation on their machine.

That's exactly the spirit of what Stallman wrote when he referred to secretaries who were not conscious of doing "programming" but were still writing programs in Emacs.

Marcin,

I'm actually working on a rewrite of the Introduction, as I progress through it. It's hard because I need to write code (and play with the kids, and work) more than I have time to read the book and write additional pages...

I feel like a lot of attempts at writing introductions do not reach their objectives because they are written by people who do not remember how it was when they needed the introduction... That's my feeling when I read the Introduction, even though I have a lot of respect for what Chassell did with that book.

Yes, of course.

The point is that someone coming to Lisp from another
language, especially (and typically) from a language
where variables are essentially local & lexical, may
have a harder time "getting it" than someone learning
programming with Lisp as her first language.

Things like list structure (including, yes, sharing
structure), symbols (named objects with properties),
dynamic scope/binding, `setq' (which can act on both
global & local vars), and even REPL/interpretation
can seem quite odd if you come to Lisp with only C
or Java or ... eyes.

Years ago I would have added higher-order and
anonymous functions to the list.  Even more years
ago I would have added recursion to it.  Depending
on the languages you are used to, the list can vary.
But Lisp is not C or Java or Haskell or ...

FWIW, I came to Lisp (and to purely functional,
logic-programming, and OOP languages) from Fortran.
No recursion, no nothin' - nada.  Another planet.
But lots of variable-value/common-memory sharing.

If you come to it from Java, JavaScript, or Python it actually shouldn't 
be that hard; they all pass data as references to structures. C and C++ 
are the only popular languages with explicit pointers. PHP is in between 
-- arrays are copied, but objects are not.

It often was back in the days of Multics Emacs (30 years ago). It was 
pretty common for non-programmers to learn it so they could customize 
their editor. Although often they just learned enough to set a few 
customization variables, not write complex extensions; that's the kind 
of thing that's now automated with M-x customize.

Declaring the variable with defvar won't change that. Anyway, the code 
we're talking about is just example snippets, not a full program.

Re: info-find-source

[Emanuel Berg]

OK, there seems to be a bit of confusion here
with respect to what I mean. So I'd like to
clarify a few thing. That said, I'm not saying
any of this to try to sway anyone. It is just
my POV.

First, I don't think info is bad in any way.
Actually, I think it is very good! To have
a uniform interface to documentation and to
have people add new pieces to it, in a uniform
way, which will then fit seamlessly, is great.
I encourage everyone who has written a larger
piece of software to do it, no doubt.

Markup and interconnectivity, if that is
a word, is also good. The man pages are both as
well and I never felt the need to browse the
groff source.

That the documentation comes with Emacs, or is
on-line (i.e., not on paper) - remember the
terrible Sierra On-Line adventure games? - is
also a good thing, even tho a web version is
also good. And because of the uniformity one
can easily use or write a tool that will
translate info material into HTML or whatever
format is desired.

The issue I have with info is that it is easy
to get lost when navigating all those node back
and forth in the tree structure, back and forth
in history, up to the parent and down to the
child until you are stuck at a leaf and you
still haven't found what you are looking for.
And you do all this with keys that you do not
use every day for editing.

Compare this to the man pages where this never
happens (because of less complexity), *or*
a plain text files, where by definition it
cannot ever happen.

But doesn't this mean the files will be very
long? Yes, and I don't have a problem with that
as this volume is linear, not broken down into
a complicated tree structure one has
to traverse to get to the rainbow's end.

The speed I've mentioned isn't the speed it
takes to execute a command, it the the general
speed of access, the human-computer interface
if you will, which again per definition (unless
your cognitive "humanity" differs from mine),
this will be much, much faster with text
because I edit text and code every day, using
the same functions and finger-habits, and no
matter how fluent an info user I'll ever be, it
could never, ever match that.

Also, how does info look to you guys? To me, it
looks like this:

    http://user.it.uu.se/~embe8573/pics/info.png

The problems getting an overview what's going
on may be related to that, as well.

I don't understand what you mean.  I usually don't understand what you
mean in these type of situations.

Info has it's own keybindings.  That can be a little tricky, since "s"
is the normal way to search rather than "C-s" or "M-s".  You can rebind
these functions though.

If you use Emacs in a GUI environment then there is more markup.  Some
things are in bold and some are in larger fonts.  I generally think this
is useful, but opinions differ.

I didn't know that!  I used to use C-s/C-r in Info all the time.  They
_do_ work there!

Then, maybe a year or two ago, I learned about the index and the `i'
keystroke, and now I can't understand how I used Info before.

Also, `C-h S', by the way.

I would really like it if someone set up a contest of "how fast can
someone use Info to search for things and come back to other things and
not get distracted by links and/or writing one's own functions to do
what you can do with stock Emacs better", and made Emanuel and me the
contestants.

What I find most useful for finding stuff: `i', combined
with better pattern-matching for the index-entry
completion candidates.

I use Icicles.  That means that index entries, which
are what `i' completes your minibuffer contents to,
can be matched with regexps, including just substrings.

In Icicle mode, `i' is bound to command `icicle-Info-index'.
Besides giving you better pattern-matching, you can
optionally have it highlight index-entry candidates
in *Completions* that correspond to already-visited
nodes.  That way, you don't end up trying multiple
index entries in hopes of getting to some nodes you
haven't already checked out.

(Wrt seeing which nodes you've visited by link color,
face `info-xref-visited' helps, but if you want that
indication to persist across Emacs sessions you can
get that (togglable anytime) with `info+.el' minor
mode `Info-persist-history-mode'.) 

Even just substring matching makes `i' much, much more
useful, IMO.  (And yes, you can set vanilla Emacs to use
substring matching for `i'.  If you don't use Icicles
or similar then this is a good workaround/substitute.)

With Icicles you can incrementally match any number of
simple patterns (progressive completion), which is much
simpler and quicker than trying to come up with a single
regexp to match what you need.  (Not to mention more
powerful, as a single regexp is limited in terms of what
it matches.)  You can also match the complements of
patterns.

Beyond pattern-matching and indicated previously visited
nodes, `icicle-Info-index' is a multi-command, which
means that you can, with a single invocation, visit
any number of nodes, matching any patterns, in any
order.

Icicles also enhances other Info commands, in particular
`g'.  When you use it you can optionally match node names
or node _content_, or both at once.

I stopped using Icicles, since I did not use it often enough to memorize
all the cool stuff in there; also, it was not as fast as I wanted.
I switched to Ivy, which is definitely less powerful, but good enough
for me, and much faster than Icicles.

In Ivy, if you search for "abc xyz", it basically transforms it to
"abc.*xyz" under the hood.  Very useful, and covers 99% of my use cases.

Still, I do appreciate Icicles - I just don't really need its power (or
at least I haven't yet discovered that I do;-)).

Further in that post I said "Icicles or similar"
to characterize such "better pattern-matching".

My point was that key `i' is typically the best
way (IMO) to find stuff in Info.  And its power is
greatly increased by libraries that provide better
pattern-matching than what is offered by vanilla
Emacs.  Icicles is one such library.

If you prefer this or that or you don't use/need
this or that, that's fine.

Wrt Icicles and other pattern-matching libraries, FWIW:

When Icicles started exploring completion and what
could be done with it there was essentially nothing
besides vanilla-Emacs completion, which was itself
coded only in C (no `minibuffer.el' library yet, no
`completion-styles' - just basic prefix completion).

And completion wasn't used much in Emacs - mainly
just for file-finding, buffer-switching, and `M-x'.

IswitchB was the only completion-related thing that
did something interesting before Icicles.  Well,
there was also `icomplete.el', which incrementally
showed you some input completions, but you couldn't
do anything with them except use them as a guide
for what to continue typing.

Over time many Icicles features have been introduced
into new packages (Ido, Helm/Anything, Ivy) - years
later.  Ivy apparently introduced `ivy-occur'/`swiper'
in 2015.  Icicles introduced it (as `icicle-occur')
in 2006 (along with `icicle-search': same, but with
regexp-defined search contexts, not just lines).

That's all good, not bad.  "Imitation...flattery."

Icicles has introduced original ideas/features,
including:

 incremental completion (matches updated as you
 type), help on individual completion candidates,
 multi-commands (multiple actions on multiple
 candidates), progressive completion (narrowing,
 successive search patterns), match complementing,
 multi-completions (matching multiple things
 together - e.g. file names & contents), cycling
 candidates, sorting candidates on the fly, saving
 completion matches & combining them using set
 operations, key completion (which also shows the
 keys currently available), fuzzy completion,
 using completion for search...

Some Icicles ideas might be hare-brained or
half-baked.  Some that I originally thought were
probably crazy have turned out to be among the most
useful.  Others I thought might be more useful were
not so.

Any or all of them could be implemented in different,
some better, ways.  And different UIs could be used
to present them to users.  And there are bugs to be
fixed...

If another package picks up this or that Icicles
idea and implements it faster or in an easier-to-use
way than what Icicles provides that's a good thing,
not a bad thing.  Improvement is good.

One of the explicit purposes of Icicles, from the
outset, has been to serve as food for thought and
experiment (for me, in particular). The existence
of Helm (formerly Anything) and Ivy is, among
other things, a testament to the usefulness of
Icicles ideas - at least some of them ;-).

Other Icicles ideas have found their way to vanilla
Emacs and to other of my libraries: Isearch+, Info+,
Bookmark+, Dired+, LaCarte, highlight.el, mouse3.el,
palette.el, synonyms.el, ucs-cmds.el.

> since I did not use it often enough to memorize all

There's really nothing to memorize.  But perhaps the
first thing is to know how to ask it.

* `S-TAB', to see all currently available keys and
  their commands (navigate the key hierarchy,
  including menus).

* `M-?' during minibuffer input for general help,
  with links to the complete help - in local files
  and on the Web - and with links to customizing
  the Icicles options & faces.

The `M-?' help also gives you the current status
of options, and (linked) key-sequences to change
status on the fly.  See attached, and imagine that
the commands and keys shown there are links that
perform their actions. 

If someone can't remember `M-?' then s?he can find
it in menu-bar `Icicles > Icicles Help' anytime.

Same with Icicles, FWIW.  That's one of the 7
"fuzzy" completion methods it supports, besides
regexp matching and vanilla `completion-styles'.
You can make it your default method or choose it
or another using `M-('.

You probably don't "need" most of what Emacs or
Lisp has to offer either.  Few (none?) of us do.
It's available on demand, for when you do.  It
doesn't bother you when you don't.  Same for
Icicles, I hope.

You are completing input for an Icicles multi-command.
To show help on individual candidates:

     Current candidate                       C-M-RET, C-M-mouse-2
     Next, previous candidate                C-M-down, C-M-up,
                                              C-M- plus mouse wheel
                    prefix-match candidate   C-M-end, C-M-home
                    apropos-match candidate  C-M-next, C-M-prior

To act on individual candidates:
     Current candidate                       C-RET, C-mouse-2
     Next, previous candidate                C-down, C-up,
                                              C- plus mouse wheel
                    prefix-match candidate   C-end, C-home
                    apropos-match candidate  C-next, C-prior
     All candidates at once                  C-! (each) or M-! (list)
     Delete object named by candidate        S-delete
     Object-action: apply a fn to candidate  M-RET

For alt action, use `C-S-' instead of `C-', but use `C-|' or `M-|',
     instead of `C-!' or `M-!', to act on all.



                    Icicles Minibuffer Completion
                    -----------------------------

Completion indicators:

  Mode line `Icy' lighter (additive):
    red = Completion available      (use `TAB' or `S-TAB' to complete)
    +   = Multi-command completion   (use `C-RET' to act on candidate)
    ||  = Multi-completion candidates  (use `C-M-j' to separate parts)
    ... = `icicle-max-candidates' shown        (use `C-x #' to change)

  Prompt prefix (exclusive):
    . = Simple completion
    + = Multi-command completion

`C-s' and `C-M-s' are normal ways of searching in Info.

In the beginning there was only `s': `C-s' searched only
the current node, but `s' searched across nodes.  As of
several releases ago `C-s' and `C-M-s' work fine across nodes.

Seriously?  Try C-s'ing the string "interactive" your way to find out
about the (interactive) codes.

In Emacs Lisp Reference:

C-x n w
M-x how-many RET
interactive RET

result: 515 hits.  The "right" one is about 1/3 down the list.

This is the nature of this kind of search.
If you are searching for an item that appears
several times, and an instance somewhere in the
middle is the desired one, then yes, search
will have to visit each preceding instance if
it starts at the beginning of the document.

This situation is a part of, but not restricted
to, the described "one file" method.

However in time you will be more sophisticated
with your searches. It'll also give you
a spacial awareness (spacial as in "space", not
special) of the document and what it contains,
which will benefit searching - your use of it -
even more.

Yes, I could train myself to do that.

But...  I have `i' in Info!  So why train myself to do something my
computer (using the information Emacs developers put in) can do better?

Because you have already trained yourself to
edit text and code and that happens every day
from now on as well. No matter how much you
train with Info, you will never get to the
text/code level. And when you "train" with text
and code, you do amazing stuff - well,
hopefully, but almost certainly something more
interesting than how to navigate a browser...

I agree with Marcin Borkowski.

I think it's a mistake to over-emphasise the editing modes, and their
keybindings.  The viewing modes and the special modes are just as
important.

I spend a great deal of time in Dired, Info, Help and reading mail.  I
also spend a fair amount of time in View, Occur, Grep, Find, Compile and
Shell.

In my experience it's worth becoming reasonably familiar with those
modes and their keybindings.  It's true that doing that means less
practice with the normal editing keybindings.  However, as you get
better at using those, each increment of extra skill comes more slowly.
You reach a point of diminishing returns.  At that stage it's worthwhile
to pay more attention to the special modes.

I don't expect you to necessarily take my advice.  I'm just giving my
opinion.

Robert Thorpe

Wrong.  Info is a special mode, so uses keys without modifiers like...
"escape-meta-alt-control-shift";-).  That's faster.  (And operable with
one hand!)

Perhaps you should look into your editing

In editing mode, `a' to `z' run self-insrt-command.  That's enough.
(Unless you use some kind of Vi(m) emulation, that's another story.)

RE: info-find-source

[Drew Adams]

BTW/FWIW, about using Info in "editing mode" or not,
here's some trivia from the past...

Info mode used to bind command `Info-edit' to `e'.

That command lets you edit Info nodes, so you can
easily update or annotate your version of a given
manual, e.g., to correct or explain something to
yourself or add more information.

The command was declared "obsolete" in Emacs 24.4.
(Personally, I see no point in that.)  The reason
given is told by `C-h f':

   This function is obsolete since 24.4;
   editing Info nodes by hand is not recommended.

   Edit the contents of this Info node.

And `e' now just takes you to the end of the `*info*'
buffer.  (On n'arrete pas le progres.)

I've seen this as well and wondered what it
meant... "By hand" - is the recommended way
having a bunch of text files and have that
compiled, or should one generate the
documentation straight from Elisp, including
docstrings and/or comments?

Also, when you could edit Info nodes that way,
where did those edits go? Using the useful and
sensible program that was the initial topic of
this thread, we find out that for example Gnus'
is here

    /usr/share/info/emacs-24/gnus.info

while SLIME is here

    ~/.emacs.d/elpa/slime-20170921.1000/slime.info

so while the SLIME's manual could be annotated
without any hazard, how will this be done with
Gnus' without sudo right and without the
changes/annotations being threatened
by updates?

AFAIK, the "recommended" way is to build Info
files using `makeinfo' with TexInfo source files.
But I'm no expert on that.

> Also, when you could edit Info nodes that way,
> where did those edits go?

You can still edit Info nodes that way.  As I
said, command `Info-edit' still exists, and it
still works.

Try it.  You are asked to confirm whether you
really want to do it.  After you make your
changes, by editing normally, you use `C-c C-c'
and enter the name of the Info file you want
to write.

If you give the name of the current file (see
variable `Info-current-file', for instance)
then you are asked to confirm overwriting it.
If you instead give the name of a new file then
you create a new Info file.

In either case you provide an absolute file name,
so that's "where" your edits go.

If you change that slime.info file and then you
download the SLIME again to the same disk location
then that will overwrite your edits.

And yes, if you want to change that gnus.info
file then you need the necessary permissions
write to that location.  Nothing new here.

But you can have Info files wherever you want.
See option `Info-additional-directory-list',
and variables `Info-directory-list', and
`Info-default-directory-list'.  And see env
var `INFOPATH'.

To be clear, I'm not encouraging anyone to edit
Info files.  I'm just mentioning that you can.

Yes of course, it even says so first thing:

    This is slime.info, produced by makeinfo
    version 5.2 from slime.texi.

OK, so it is the *.info files* that one is
disencouraged from editing? Well yeah, why
would you do that?!

The "by hand" phrasing is where the confusion
begins because it seems to imply there is
a better way to "edit" them. But to me it seems
totally backward to edit the result of
compilation and I don't think I ever did that
because wouldn't not only update but also
recompilation overwrite the edits?

In general one should edit the source! and here
one could simply keep a text file with any
extra material.

That command exists because Info files predate the makeinfo program;
the first Info files were made by hand, because makeinfo didn't yet
exist.

Maybe `Info-edit' existed before `makeinfo' and `Texinfo';
I don't recall.  But all three are very old.  I recall all
three back in the 80s, if I'm not mistaken.

And `Info-edit' was not deprecated until recently.  So
unless my memory is mistaken here, the lack of `makeinfo'
was not at all the reason that `Info-edit' remained
available (and bound to `e') all those years, even if it
was the case that it existed before `makeinfo'.

`Info-edit' can be useful for someone to simply modify
or add a bit of text, without needing `makeinfo' to be
available (installed).  IOW, it's use cases were never
limited to hand-creation of entire manuals.  That would
give a very false impression, IMHO, of what this command
was/is about.

For one thing, `Info-edit' is used from Info.  I'm not
sure it was ever intended to be used to write whole
manuals.  I'd guess that at least that was not the main
use case, especially all those years long.

Quick correction/annotation/addition to one's
own copy of a manual.

Versus re-creating lots of stuff (after having
installed `makeinfo', if it's not installed
locally).

The existence of `makeinfo' does not obviate
the usefulness of `Info-edit'.

When that result is human-readable text it's
not a big deal to edit it.  Of course, if
you want the change to be reflected more
globally or to be shared etc. then you want
to only modify Texinfo source and generate
Info output.

You yourself argued for using *.info files in
plain editing mode (e.g. after `C-x n w').
Something like `Info-edit' is nowhere near as
extreme as that.  It's used for simple, quick
one-off changes or additions.

One doesn't have to argue _against_ generating
Info from Texinfo to see some utility in a 
command such as `Info-edit'.  Granted, that
utility is limited, and most people have never
even heard of it.  But that's not the same as
saying that it has no raison d'etre.
____

I mentioned that Info+ has a command,
`Info-merge-subnodes', for creating a
plain-text, prettified merge of Info nodes
(even a whole manual, but more typically a
section of a manual, however small).

Such a flat buffer can be useful sometimes
(e.g., plain-text printing, some kinds of
searching, sending excerpts), but I wouldn't
argue that `Info-merge-subnodes' is a _super_
useful command.  Some commands have limited
usefulness and use cases.  `Info-edit', like
`Info-merge-subnodes' is one such.

Well, it is a thought to read the documentation
that way, and have the whole program file in
a single buffer, which operates like a regular
file and doesn't disappear when you do something
else or bring something else up thru some
interface which you aren't that apt with...

But after doing `C-x n w', and even `text-mode'
on top of that, you still have to disable

The really short and close shortcuts, which
involve either a single C or ditto M, and then
a single key, which doesn't require hand
movement, e.g. M-i, M-k, etc. - these are not
slower to any practical extent, and whats more,

This is the point.  Underneath, Info is *still* linear.  You can search
it with C-s/C-r, if that's your way.  Also, you can bookmark Info pages
(using Emacs stock bookmarks or bookmark+).

I can't see *any* gain from your function.  And if I really wanted
something like that, I'd probably use "no new keystrokes to learn"
(using your own words!) and stick with plain old `C-x n w'.

Please try it out and tell me how your solution is superior.

Of course, because otherwise it couldn't be put

in order!

(Here "Info" means the data, or documentation,
not the browser or Emacs mode.)

OK, the gain is it brings up the raw source
file associated with the info file you are
browsing. Or at least that is the purpose as
I haven't had time testing it a lot.
But because there exists a correlation between
the source file and what is displayed with the
info browser, the Holy Grail cannot be farther
away than the expected initial problems.

Actually, I cannot see "any gain" from
displaying the data as a tree! The only gain
I can see is hypertext. I see the point of
that, but I see that as something similar of,
you ask a person "how do you do X? what do you
need to do it?" and s/he says "Ask P about
that. Or go to the HW store and ask them" - if
you on the contrary know what data you desire,
and you know where it is, there is no need for
any form of hypertext, be it "On-Line" or on
the Internet. Instead of following links you go
directly to the Rainbow's End, acquire the
item, and return.

The drawbacks from using Info compared to text
are it's a mode from which you have much less
experience and thus much less fluency, and it
isn't always true that all your tweaks and
extensions fit seamlessly into info, while this
cannot be an issue for text, as that is the
original habitate anyway!

You don't have to do `M-x text-mode RET' after
you do `C-x n w'?

Hypertext is an important gain.  Convenience is another: many keys in
Info do not need two keystrokes (`i' compared to `C-s'), so I can use
Info with one hand.  (And yes, I do it quite often.)

But Info derives from special-mode, and shares many keys with other
modes derived from that, like eww, dired etc.

That's the benefit: with text only, source file

How to get back to a place in a buffer, or: what is a window configuration?

[Marcin Borkowski]

Hi all,

sometimes I work on a particular place in some buffer, and Emacs for
some reason scrolls me out of that place.  I want then to get back to
it.  Is there a way (in stock Emacs or with help of M?elpa) to
accomplish that?

Bonus points for a package/command which /temporarily/ disables C-v/M-v
and other commands that might result in scrolling text in the window.
(Narrowing to what is currently visible should do the trick, so
a combination of M-r, C-e and C-SPC would probably do what I want.
Coding that is three minutes, but maybe someone did it already?)

Note that it's not the same as keeping a position in a register.
A simple experiment shows that keeping a /window configurations/ seems
to do what I want, but from reading the manual I'm not sure what
a "window configuration" really is.  What does a "window configuration"
consist of, exactly?

TIA,

Re: How to get back to a place in a buffer, or: what is a window configuration?

[Kaushal Modi]

Here are a couple of things that might help you:

(1) Setting scroll-preserve-screen-position to a non-nil value.
If you happen to C-c/M-v so that the point changes its position, but if the
above is set to t and you reverse the scroll direction, you will find the
cursor at the exact same position where you last left it.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Scrolling.html

(2) Use C-u C-SPC
When you do large vertical positions, emacs auto-saves the previous marks
to the mark-ring. It is very convenient to jump back to those older marks
by hitting C-u C-SPC.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Mark-Ring.html

(3) Use winner-mode
This is a golden mode, used to conveniently jump back and forth window
configurations. The awesome thing is that you do not need to manually save
those configurations. All window configuration changes are auto-saved.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Window-Convenience.html

(4) Create mini wrapper functions to scroll current/other window without
moving the cursor position. I have the below in my config.

;;; Scrolling
;; Keep point at its screen position if the scroll command moved it
vertically
;; out of the window, e.g. when scrolling by full screens using C-v.
(setq scroll-preserve-screen-position t)

;; Scroll without moving the point/cursor
(defun modi/scroll-up (ln)
  "Scroll up by LN lines without moving the point.
If LN is nil, defaults to 1 line."
  (interactive "p")
  (scroll-up ln))

(defun modi/scroll-down (ln)
  "Scroll down by LN lines without moving the point.
If LN is nil, defaults to 1 line."
  (interactive "p")
  (scroll-down ln))

(defun modi/scroll-other-window-up (ln)
  "Scroll other window up by LN lines without moving the point.
If LN is nil, defaults to 1 line."
  (interactive "p")
  (scroll-other-window ln))

(defun modi/scroll-other-window-down (ln)
  "Scroll other window down by LN lines without moving the point.
If LN is nil, defaults to 1 line."
  (interactive "p")
  (scroll-other-window (- ln)))

;; Below bindings are made in global map and not in my minor mode as I want
;; other modes to override those bindings.
(bind-keys
("<C-M-up>"    . modi/scroll-down)
("<C-M-down>"  . modi/scroll-up)
("<C-M-left>"  . modi/scroll-other-window-down)
("<C-M-right>" . modi/scroll-other-window-up))

I know that, and I set scroll-preserve-screen-position to t in my
init.el a long time ago.  But thanks anyway, it is not very well known!

I know that, too, and I use it often.  But point position is not what
I'm asking for; I also want the point to get in the same place onthe
screen, IOW, I want to preserve the first visible line.

I've heard about it, now that you recommend it, I'll try it out some

I also had such functions some time ago, I must have deleted them from
my config.  OTOH, C-v/M-v with prefix arg seem to do the same, so hey
seem a bit redundant to me.

A place (position) in a buffer has little or nothing to do with
windows.

It sounds, from the rest of your question, like you are more
interested in restoring a window configuration.  But your
question is still unclear, to me.  Hopefully, Kaushal's answer
gives you what you want.

Getting back to a buffer position is simple - you can use
temporary bookmarks or the mark ring or other methods.  But
I don't think that's really what you're asking.

I don't see the connection between that and your request
(apparently) to restore a window config.  Is it that you really
(or additionally?) want to prevent moving `window-point'?
or perhaps prevent it from moving too far?  The underlying
question or use case is not clear to me.

If narrowing to what is currently shown in the window is
what you're looking for, then yes, you can easily code that.

(If you use library zones.el then you can easily flip among
multiple narrowings, in case that is related to what you want.
https://www.emacswiki.org/emacs/MultipleNarrowings)

By "place", I meant two things: (1) where the point is and (2) what is
the first (topmost) actually displayed (visible) line.

More or less.  I'm now convinced that window configurations were what
I was looking for.

My goal (though probably not my words;-), sorry) is simple: I want the
"place" (in the sense of the above definition) to stay the same, /or/
I want to be able to easily restore it.  The former should be doable
with narrowing, the latter probably with window configurations.

I heard about it, though I don't really see much use (for me, not in
general).  OTOH, I use narrowing quite a lot, so maybe I could give it
a try.

I learned about it today while rereading the manual.  Very useful
indeed!

Well, now I see it...

But look at this:

,----[ (emacs) Configuration Registers ]
| You can save the window configuration of the selected frame in a
| register, or even the configuration of all windows in all frames, and
| restore the configuration later.  *Note Windows::, for information about

`----

,----[ (emacs) Window Convenience ]
| Winner mode is a global minor mode that records the changes in the
| window configuration (i.e., how the frames are partitioned into
| windows), so that you can undo them.
`----

See?  Basically nothing in the /Emacs manual/ explains precisely what
a "window configuration" is.  On the other hand, the /Elisp reference/
is pretty clear.  I'd consider this a bug in the docs: a /user/ should
not need to consult the Elisp reference.  I'll try to come up with
a patch for the docs soon.

If it doesn't help, don't use it. ;-) The idea is simple: Emacs
lets you narrow to different restrictions, but there is only one
level of widening: `widen'.  This is analogous to simple copy+paste
systems: you can copy different things at different times, but when
you paste you get just the last thing copied.

With this extension to narrowing: when you narrow, the restriction
is pushed to a ring - analogously to copying/killing text to the
`kill-ring'.  And just as you can yank anything that is on the
`kill-ring', so you can restore any restriction (narrowing) from
the ring.  (And you can have multiple rings, buffer-local or not.)

As for whether you will find that useful: it might depend on how
much you use narrowing.  And perhaps also on what you are used to
(habit).  People used to simple copy+paste might not find the
`kill-ring' very useful at first...

What do you think a user should know about what a window config is?
That's the question, if you think the Emacs manual needs more info.
(`M-x report-emacs-bug').  (Note that there can also be links between
the manuals.)

I used to have the problem.  I found it was caused by using
auto-revert-mode.  It was either applying auto-revert-mode to dired
buffers or applying it to buffer lists that caused the problem, I can't
remember which.  Try disabling those and see if it fixes it.

Reverting a Dired buffer centers the line that was current, and puts
the cursor at the beginning of the file name on that line.  This happens
regardless of how you revert (using `g' or using `auto-rever-mode').

For buffer reverting, you have `after-revert-hook' (and `before...'),
which you could no doubt use to counteract any such window and point
movement.

Overriding emacs key bindings

[xiongtk]

Hi! I'm in a situation where I would like to override the following key
binding:

    /Applications/Emacs.app/Contents/Resources/lisp/international/mule-cmds.el.gz

    (define-key global-map "\C-\\" 'toggle-input-method)


Since this file is read only and it's not inside .emacs.d, I do not
want to change it directly if other solutions are possible.

I've tried with writing the following line in my personal customization
file:

    (define-key global-map (kbd "<f8>") 'toggle-input-method)
or
    (global-set-key (kbd "<f8>")  'toggle-input-method)

(I've tried both.)
Which assigns f8 to be the key binding.

However, checking the key binding with C-h a toggle-input-method gives me
the following message:

    Type M-x apropos-follow on an entry to view its full documentation.

    isearch-toggle-input-method   M-x ... RET
    Toggle input method in interactive search.
    toggle-input-method           <menu-bar> <options> <mule> <toggle-input-method>, <f8>, C-\
    :around advice: `ad-Advice-toggle-input-method'


Apparently my method does not override the original key binding. Any
suggestions?

P.S. About why I want to do that, I use evil-leader which uses "\" as
the leader key. To execute evil-leader key bindings in non normal mode of
evil-mode, I need to use C-\ as the leader key. So it conflicts with
the default key binding for toggle-input-method.

Correct.  It just adds another binding.

Good call! Because then you'll loose it for
example when you upgrade Emacs, and each edit
would require a sudo detour...

Instead of (kbd "<f8>"), you can do [f8].

(But: I don't recommend using the function keys
as they are remote (i.e., require arm movement
as opposed to just finger ditto, which in turn
implies a reset to typing position) - also they
are confusing (too alike) and thus difficult to
remember. And they don't work in a VT Emacs
instance! - not without special efforts [1]
at least.)

By "override", do you mean the new keystroke
won't work, or the old keystroke remains?

If the old keystroke remains, that is normal.
You can unset it like this:

    (global-unset-key "\C-hh")

If the new keystroke doesn't work, sometimes it
is the case that a *local* keymap has that key
assigned. Changing the global keymap doesn't
change the local map, of course, and the local
map has priority, as far as locally goes!

Here is some code to automatize setting
a global key, and then disabling the same key
for the desired local modes - if you want the
global key to be in effect there, as well.
Use the functions in the order they appear.

(defvar super-global-keys '())

(defun super-global-set-key (key function)
  "Make a super global KEY that invokes FUNCTION."
  (global-set-key key function)
  (add-to-list 'super-global-keys key) )

(defun disable-super-global-keys (&optional map)
  "Disable MAP super global keystrokes, so they can be assigned."
  (dolist (k super-global-keys)
    (define-key (or map (current-local-map)) k nil) ))

To each his own. And Emacs makes that much
easier to achieve. By changing Emacs, you
become a better programmer and better computer
user, and even Emacs gets better, until the
point you realize there is already a built-in
function, or module, that does what you have
done, only better, and then it all starts over
at a higher level... Because, if anything can
start anew, then everything must continue!

That said, if you rarely use the function,
there is no need for a shortcut. Remember,
"optimize the common case".

If you think it is to much to type the actual
function name, instead make an alias - or
several! You'll find that it is actually faster
to invoke as it is easier to remember and,
again, does not require arm movement way from
typing position.

Why several aliases? Because sometimes you
remember "test-colors", and sometimes
"color-test" - with aliases, they can all be
correct! But here, compare: will you remember
that "color-test" years ago was assigned F6?

So, e.g.,

    (defalias 'download 'w3m-dl-dwim)
    (defalias 'dl       'w3m-dl-dwim)

Regardless, I don't think you are running out
of shutcuts :)

Many shortcuts are assigned to stuff you never
use - you can replace those. It is not because
the stuff is bad - it can be just appealing to
another personality, or involve technology you
just don't use!

Here is a tool - eval, invoke, and start
hammering away, and you'll see:

    (defun show-key-command (&optional the-key command)
      (interactive)
      (let*((key-prompt           "(hit key! or C-g to quit)")
            (prompt               (if command (format " %s   %s " command key-prompt)
                                    key-prompt))
            (key                  (or the-key (read-key-sequence-vector prompt)))
            (new-command          (key-binding key))
            (command-or-undefined (or new-command "undefined")) )
        (if the-key (message "%s" command-or-undefined)
          (unless (equal key [7]) ; [7] is C-g
            (show-key-command nil command-or-undefined) ))))

If you really *do* run out of shortcuts, get
a new prefix key, e.g. C-o which is short and
close - check your hands when at asdf jkl; and
note the required movement to strike C-o!

Now even a new world of shortcuts opens. E.g.,

    (define-prefix-command        'C-o-prefix)
    (global-set-key        "\C-o" 'C-o-prefix)
    (global-set-key        "\C-ow" #'window-increase-size)

Personally, I'm very used to C-o being open-line.  That said, I agree
with Emmanuel in general about this.

There are a lot of options that people don't consider.  Emacs reserves
all keybindings of the type C-c C-<something> for modes.  However, if the
second key doesn't begin with ctrl then the user can use it.  The entire
C-c <something> keymap is reserved for the user.  The something can be
any key that's not prefixed by ctrl or meta.  Any key works, even the
numbers and symbols on the keyboard.  Capitals and small letters aren't
treated the same, so there's a huge space there for new keybindings.
Then there are rarely used prefix keys, like the key for marking text,
you can attach stuff to that one.

That is generous, however Emacs is even more
generous and the user can assign any shortcut.

I think C-o is better as 1) o is easier to hit
than c, and 2) with C-c, both keys are on the
left hand side (little and index finger hitting
the keys), while with C-o, there is a pleasant
combination of left and right, and the left
index finger remains at f!

(Now in Russia, there was once a civil war that
lay the entire land to ashes, and the dispute
was how to make the cross sign - either
initially horizontally, or vertically!
Talk about stupid...)

But I also suspect C-c "single key" is
underused. Luckily it is just a key so it
doesn't have hurt feelings.

Absolutely, you don't have to hold a Ph.D.
in combinatorics to understand there are more
combinations than 99% of Joe Elisp Hackers
could ever use sensibly!

Because Emacs is like a workshop filled with
tools, or a library but not with fiction but
formulas and methods and strategies. You can
benefit several lifetimes (if you live that
long) from them tools and books, but you still
will never have laid hand on every single one
of them. It is just the way it goes.

While I do agree that a wide range of user bindings are available with C-c
prefix, I would not recommend blindly using all available "C-c SYMBOL"
bindings without checking of org-mode already uses them especially if you
use org-mode a lot. I now first check if a new binding conflicts with
org-mode before creating a new personal C-c binding.

You can also check out the key-chord package from Melpa for a wider range
of bindings.

Sure, if you use a mode that assigns certain keys, and if you want
to use those keys for that mode, then use those keys for that mode.

But if you want to use those keys for something else, you can
always bind different keys for use by the mode.

Interesting - in other words, it is _org-mode_
that decides what keybindings you use...

Another idea, if you look for some intuitive
degree of consistency, is to identify "key"
concepts. For example, one such concept is "to
execute". In this message-mode, C-c C-c is to
send the message. I'd say that is to execute,
in the setting of typing a mail!
Likewise a piece of code - to execute is either
to launch the program, or to compile it.
Perhaps it is launch if it is a shell script,
but compile if it is LaTeX source! A global
DWIM function with branching can do this, or
each mode can have its own function that
locally is associated with C-c C-c. In Dired
(and a Gnus summary for that matter), there are
a bunch of things you can mark the files
(posts) so that it will happen when you -
execute. And in Emacs-w3m, you can fill forms
with data and submit with the same key!

Another axis of intuitiveness is the modes when
there is no typing. Here, the whole keyboard
can be used to fire of defuns! But even cooler
if this mirrors, only simplifies, the standard
keystrokes. Say you have scroll up one line
with M-i, and ditto down with M-j. You have
this all over Emacs. [1] But in w3m, which
doesn't require typing when you "browse" (yuk,
that word!) - here, make it super-comfortable
by keeping the M-i and M-j, but supplementing
with i and j, to do the same thing!

So there is no need to fear getting in the way
of what is already there. Instead think what
you would like to do.

You're right.  I didn't know that Org uses those keys.

No, it does not.  Emacs does not reserve any keys from users.
Users can bind any keys they like.

What Emacs reserves (by convention) are keys from modes.
It says that major modes should use only these keys and
minor modes should use only those keys.  And neither
major nor minor should use a third set of keys, which are
_only_ for users (again, by convention).

But users can use _any_ keys.

> However, if the second key doesn't begin with ctrl then

Doesn't matter what the first or second key is.  Users
can use all keys.  They can override any key bound by
any mode.

Thank goodness.  It would be silly if some keys were
reserved for modes and not allowed for users.

Are those "Emacs conventions" - and not just
those who deal with keys -
summarized somewhere?

Because they are obviously good to be aware of,
so when you disregard them, it is something you
do because you think it'll benefit you, and not
because you are unaware of something that on
the contrary makes sense...

(elisp) `Key Binding Conventions':
http://www.gnu.org/software/emacs/manual/html_node/elisp/Key-Binding-Conventions.html

> Because they are obviously good to be aware of,

Yes, they are good to be aware of.  But again, they are
for someone writing a library for more than personal use.
They are in no way restrictions on users.

There is no convention (that I know of) that restricts
key bindings for users or even suggests that users
should stay away from certain keys.

The exceptions I can think of, in terms of suggestions,
are `C-u' and `C-g'.  You might get into some difficulty
if you try to bind `C-u' (and a few users seem to want
to do that).  You can use another key in place of `C-g',
but there are some hard-coded bindings of `C-g' to its
usual behavior, AFAIK.

I would recommend that no one try to use `C-g' or `C-u'
for something else.  (But there is no restriction against
trying to do that.)

OK.

No doubt, disregarding conventions in code that
is supposed to be shared - you should have
a very good reason for doing that! (The
assumption being the convention makes sense.)

Still, there is a hesitation in my mind doing
a to sharp division between libraries that are
professional, and then the user stuff... The
user stuff is the best school. So it is a good
place to start acting like a skilled
programmer, and that skilled programmer may
well write or contribute to a library, and that
doesn't have to take three decades like some
people think....

As they say in boxing, "you want to be
a champion? Start acting like one, today".

So a list of conventions, good habits, known
pitfalls, etc. is a good idea. (Perhaps it can
in large parts be compiled from different parts
of existing material.) Just a thought - I'm not
up for the job myself :)

But here is one thing that might help for code that
is a package:

    (defun check-package-style ()
      (interactive)
      (checkdoc-current-buffer t) ; TAKE-NOTES
      (message "Style check done.") )

By the way, if you put that into a package and
run it on itself, it says all interactive
functions should be documented, I think.

But with docstrings, there is a wierd behavior
- often, this is the "error":

    First line is not a complete sentence

What does that mean and what is the definition
of a complete sentence - besides that it should
end with a full stop?

Well, I suspect Emacs can only check whether it ends with a full stop,
but the idea is of course also that it is a full sentence from a
grammatical point of view. In essence, it should convey a clear and (in

That was I joke which refered to that the error

Because I get that error even tho there is
a full stop.

Right, but if it cannot check that, it might as
well *always* report "Use correct English!"

No, I think it does something more sensible,
only it fails to communicate what exactly so it
is only confusing at this point.

Wait... now I understand, I think. One gets the
error if one ends the first line with \n!

But if a user binds a key that's supposed to be for modes, and then they 
load a mode that also binds that key, they'll have a conflict. The point 
of these conventions is to avoid conflicts like this.

If you don't mind losing one of the mode's keybindings, that's fine, but 
you should do it with full knowledge of the potential conflict.

Thats exactly right.

Part of the reason a convention is useful is
that the convention itself makes sense, but
part of it has little to do with the particular
definition, and the usefulness lies in the
status as convention as such, and likely some
other definition would have worked just as
good...

Ha ha, "Apps" :)

Fittingly, that key doesn't work with Emacs in
a Linux VT - not without the efforts already
mentioned in this thread.

AltGr and the key with the MS flag on it
reports the same key, C-@.

But showkey(1) gives three different values for
them so all three can be put to into different
action - only, IMO they are not good keys so
I wouldn't bother...

On my keyboard the menu/apps key is next to ctrl.  While your fingers
are on the main part of the keyboard you can press ctrl using the bottom
of your index finger, the part between the finger and the palm.  You can
press the menu key in the same way, so I find it a useful key.  It
depends on your preference, and to some degree on the size of your
hands.

Yes, deeming from your image, I think we have
the same type of keyboard.

For many years I had a lovely Sun keyboard but
step by step it disintegrated and now I have
a mundane keyboard, along with the Microsoft
flag, and even the Swedish char layout!

Hideous - but I suppose it won't matter, as
I know where the US layout keys are by know.

Perhaps I should do like in the Angelina Jolie
movie, where the dude sprays his keyboard in
a uniform color. I did that myself with
a bicycle trailer when I created my new
office [1] so I don't see why it shouldn't
work again.

... really? You do that? Far out :) Does that
have a name? Let me reveal my inexperience by
admitting I never heard of it. Myself, my claim
to fame is my dynamic signature, below - cute,
to say the least :)

Speaking of keys and stuff I never heard of,
the AltGr key ows its name from the following
fragment of computer history:

    AltGr was originally introduced as a means
    to produce box-drawing characters, also
    known as pseudographics, in text
    user interfaces. [2]

Ah, that one, thanks!  I had no idea it had anything to do with marking
text.  I used to bind it to various stuff in my WM; this way, I could
release all those precious keys usually taken by the WM, like M-TAB.

Why use such a key bound to such a useful command (`open-line') for
a new prefix key‽  Especially when C-z is totally useless (and in an
extreme case when it is what you want, `suspend-frame' is duplicated on
C-x C-z anyway)?

Personally, I never user use `open-line'.
I actually don't know what I do instead:
`C-a RET', perhaps?

But I do have `C-o a' undefined, so I'll put
`open-line' there, and perhaps this "opens"
a door to a new world of editing proficiency :)

If you use C-o for `open-line' all the time,
obviously it is not a good prefix key, unless
you can assign `open-line' another shortcut
just as good, and then reprogram your
brain/fingers, of course.

As for C-z, I like that even less than I like
C-c, for all the same reasons I dislike C-c
*plus* it involves the little finger (compared
to the index finger) and the keys are even
closer than C-c where they are too
close already.

If remembering is an issue (as in seldom used commands), hydra comes to
the rescue.

But I also agree on the point that there's nothing wrong with using M-x
and a descriptive name for rarely used commands.  Though long names
don't bother me beacuse autocompletion (either vanilla Emacs, or

Autocompletion I don't like - it reminds me of
my VB5, Eclipse, MS SQL Server, and .net days
(which all were few but traumatic) - for sure,
in Emacs it is much better, as with TAB it
happens at your discretion, and not instantly,

"something-groff", and 2) I like to think my
memory improves from memorizing either the long
names, or, if too long, my aliases which are
shorter and should click with my memory better
as 1) I wrote them, and 2) the correspond to
my thinking.

Now this message is 1) written, and 2) sent.

Opening a bookmark in the init file

[Robert Thorpe]

For years I've setup Emacs so it presents me with my ToDo list at
startup.  It doesn't put me in the right place in the file though.  I
can bookmark the place in the file, but using bookmark-jump in the init
file doesn't work and it doesn't work in emacs-startup-hook either.

I know I can use desktop.el to save and restore everything.  I don't
want all the other buffers saved and restored though.

Why doesn't it work in your init file? Of course you will need to
load your bookmarks file before trying to jump to the bookmark.

But doing that and jumping to a bookmark is just invoking Lisp
functions.  Nothing special - you can invoke pretty much any
Lisp functions you like from your init file.

I suggest that you specify in detail what you have tried, and
perhaps people here will be able to help.  If you do that, keep
it simple - an init file that does only what you are trying to
do in this regard.

Start by just trying to jump to a simple bookmark from your init
file - not a special bookmark (just a static file position),
not involving any other code, whether Org to-do stuff or anything
else, and with a bookmarks file that contains very little - maybe
only that bookmark.  And start from `emacs -Q`, of course.

That was the problem.  When I loaded the file with (bookmark-load
"~/.emacs.bmk") it worked.

This fix only worked for a while.  In my .emacs file I put:

(bookmark-load "~/.emacs.bmk")
(add-hook 'emacs-startup-hook '(lambda () (bookmark-jump "TODO")))

It worked for a few days but I noticed Emacs was becoming slow to
startup.  Today I had to restart Emacs a few times.  The last time it
took several minutes to starts.  The bookmark file was the culprit.  For
some reason every entry had been duplicated with the text <2> in front
of it.  Then it had been duplicated again with the text <3> in front of
that, and so one.  This caused by bookmark file to double in size on
every restart until it was ~50MB long.  I found that the two lines above
are the cause.  If you add a bookmark-jump to emacs-startup-hook then
something goes wrong somewhere.

For some reason, you chose to call function `bookmark-load'.
If you do that it behooves you to check its doc first ;-):

,----
| bookmark-load is an interactive autoloaded Lisp function in

| 
| It is bound to <menu-bar> <edit> <bookmark> <load>.

| 
| If you load a file containing bookmarks with the same names as

`----

See the last paragraph.  You are loading your bookmark file more
than once.  Most likely you are doing an explicit `bookmark-load'
when your bookmark file has already been loaded.  Don't do that. ;-)

You can use function `bookmark-maybe-load-default-file'
instead of `bookmark-load'.  (There is also variable
`bookmarks-already-loaded', but you should not need to check it.)

But before bothering to fiddle with such things, check what you
are really doing, to see how/why/where else you are loading your
bookmark file, and perhaps simplify your code accordingly.

I'm loading the bookmark file because it doesn't work otherwise.  If I
just do:

(add-hook 'emacs-startup-hook '(lambda () (bookmark-jump "TODO")))

Then Emacs gives an error "Invalid Bookmark TODO".  It seems that the
bookmarks are loaded after emacs-startup-hook, which is odd.  If I load
them before it works though.

Many functions call `bookmark-maybe-load-default-file' (which loads
the bookmark file if it has not been loaded).

If you don't want to call that instead of `bookmark-load' then
try to find out what, during your startup, loads the file.
Do `M-x debug-on-entry RET bookmark-load RET' to see what calls
`bookmark-load' the first time.

There is no harm in calling `bookmark-maybe-load-default-file'.
I mention trying to find out what was causing the first load as a
way of helping you understanding what was happening.

Stupid me.  Pressing RET on the link to the footnote jumps there,
pressing RET again (on the footnote number next to its text) gets me
back.

Cool: most likely there isn't a better example for how
to properly use Elisp for real software, than Emacs
and the associated software and libraries.

But even so, what if some guy is the other way around,
e.g., he prefers `garbage-collect' to `goto-char'? Is
that easily rerouted in some automatically generated
(but after that manually editable) abbrev table?

> so probably somebody has done something like this

Yes: I've seen something similar but I think that was
the typing of commands after M-x, and not the whole
Elisp language when typing it in a buffer.

Personally, though I think this an interesting/cool
project, I don't have a problem typing (on the
contrary, I like it very much) and I am actually very
fond of the Elisp verbose style (compare the C style
with very short names, with "undelimited"
abbreviations and often digits and such in between and
all over) - I mean, I like C, and when I do C I do
that as well, but when I do Elisp, I really enjoy
those long this-is-a-function-that-does-something - it
isn't too slow to type as long as it is normal words
and normal chars, not
asymmetric-asynchronous-continuous-anonymous or
anything.

My second concern is that if this is abbrevs, don't
you get crazy from them expanding all the time as you
type?

But anyway, thumbs up for activity and zeal!

False assumption: that Emacs libraries contain good practices only.  I
know you dislike Emacs.SE, but there was a question there about good
Elisp code to read (to learn Elisp), and someone warned about reading
Emacs code (especially older libraries).  Recently, I grepped the Emacs
Lisp sources for occurences of `mapcar', and there is *no* consistency
in e.g. using ' versus #', or quoted lambdas (which I hear are a no-no
unless in special circumstances, like macros).

Re: Abbrevs for the most frequent elisp symbols

[Robert Thorpe]

There are the dynamic abbrevs facilities, M-\ and C-M-\.  They search
through the open buffers looking for completion candidates.  They're
included by default in hippie-expand's completers.  Personally, I prefer
that style of completion to abbrev.

You could use a similar strategy with normal abbrev though.  Load up a
set of Elisp files that are typical of your personal usage.  You could
then use the code in dabbrev-expand or dabbrev-completion to find the
completions you want.  You could wrap that in a bit of Elisp and run it
once to generate a table, then decide on the abbrevs manually or by
taking a prefix.

Martin mentions that the Emacs sources themselves contain some code
that's frowned upon these days.  That's true, there are many old parts
of Emacs.  The parts that are new are a good guide though.  There are
some peculiarities even there though, Emacs code doesn't use certain
features to avoid loading them when Emacs starts, easymenu for example.

And the little-known but there-forever and useful `dynamic-completion-mode,
from built-in library `completions.el'.  (The file Commentary is the doc.)
The keys for it are, by default, `C-RET' and `M-RET'.

The use is different, but yes, very useful.

Indeed.  But to a large extend, for quoted function names, the
difference between the two is a question of taste.  IOW there are
usually much bigger elephants to deal with before it's worth worrying
about such details.

AFAIK there have been no quoted lambdas left in Emacs's own code for
quite a few years now.  There are still some backquoted lambdas which
should be converted to closures, admittedly (usually it's either
because converting those packages to lexical-binding is a bit more
tricky than usual, so it hasn't been done yet, or it's because the
conversion can't be done because the package is also distributed
outside Emacs and needs to work on Emacs<24).

That also works in Elisp buffers, actually: type "(g-c" and then M-TAB
and you'll be offered completion on all the
g<something>-c<something> functions.  It's not really the same as the
OP's abbrevs, tho, because there are *many* functions matching "(g-c".

No offence meant; Emacs is older than many people on this list
(including me), both the language and the libraries did evolve quite a
bit, and then there is the problem of manpower - no surprise some code
in Emacs is rather dated.

Maybe - I just wrote about something I noticed, I don't read Emacs
sources on a daily basis (and I'm not competent enough in Elisp to
notice many things).

I have Emacs 24.3, maybe that's the reason.

No: "quite a few years" here means something like since before
Emacs-24.1, IIRC.  If you see a quoted lambda in Emacs's code, report it
as a bug.

Something like this could be added, but I don't see
the reason, because I think the elisp sources are
fairly representative of the usage frequency of symbols.

I'm pretty sure most people use goto-char more often
than garbage-collect.

The aim was to provide a very convenient way to type
the most frequent symbols. For the less frequent one
you always have some kind of completion.

I was tired of typing save-exursion, etc. all the time
and while I use completion (company) for elisp symbols
it's still cumbersome to type for the most frequent
symbols while typing simply 'se' is very convenient.

There was one problematic abbrev I found when I tried
it 'if' which mapped to some lesser used function, don't
remember which, so I deleted it manually.

Otherwise, the abbrevs are surprisingly unique and 
didn't interfere with normal typing, though I haven't
tested it extensively.

No, not really. I supported it from day one (verbally,
I mean). When they do a message-mode/Gnus-like
interface, I might even use it! But only once or twice
for my favorite questions so they perhaps reach a
wider audience... I can't say I like it but I don't
dislike it.

That reading Emacs code in any way should be harmful
of course I don't believe in. I always emphasize
activity rather than consumption but if there is room
for any consumption reading Emacs code is a good
choice for any programmer, no doubt.

Yeah, I have no illusions that it is consistent or
perfect in the abstract sense. Of course it isn't as
so many people worked on it. Still, the definition of
good software is what it can do, or, what it enables
you to do. You can't beat that. It is good.

You might like sx.el.
I don't know if I'd call it gnus-like, but it's pretty good.

Yes, I found it in melpa ("sx", version
20150105.1006), but it requires "let-alist-1.0.3"
which "is an orphan package" - what does that mean? no
parents as in dependencies up the ladder? - but worse,
the package itself seems to be missing. Here is what
Help says:

    Status: Orphan.
    Archive: n/a
    Summary:

And I can't find it, either.

Anyway, I would really push for sx and other attempts
to access/use the SX sites from Emacs, be included in
Emacs when they reach maturity, if they didn't
already...

Ha! melpa sure is fun. How about this:

    sunny-day-theme ... Emacs24 theme with a light background.

It's on GNU Elpa, do you not have it configured by any chance?

What's wrong with typing? All those expanders are like
ants in a colony. I want it to be a bare mountain and
a clear horizon. I don't want to type less. If you do
it 18 hours a day I can see the point: it could save
your fingers from disintegrating. But I don't do it
all day long so when I do it I think typing is
superior to all those schemes. But the OP is of course

when you gotta have a variable value for a symbol name

[Buchs, Kevin J.]

I want to evaluate (kmacro-name-last-macro variable), where I want the 
value of "variable" passed as the symbol name. Despite years of trying, 
I don't think I ever really conceptually "got" the distinction between 
symbols and variables and that seems to be critical here. I'm working 
with the code below, but it is not suceeding in naming the macros (no 
error messages, however). Of course (kmacro-name-last-macro 'my-macro) 
works just fine.

Change `make-symbol' to `intern' and you're good to go.  `make-symbol'
returns an uninterned symbol.

Lisp is like the insides of a compiler.  There's a big hash-map, the
obarray, which is the symbol-table.  It stores strings along with some
information about them.  These strings are "symbols".  There are three
pieces of information: the symbol's value as a variable, the symbols
value as a function and a property list.  An interned symbol is one that
is an entry in the obarray (there can be multiple obarrays though that
feature isn't used much).  An uninterned symbol is one that sits by
itself, it has the same parts as usual: string, function entry, variable
entry and plist, but it's not attached to an obarray.  If we have a
function call: (foo bar 'baz) then lisp treats each of these symbols
differently.  It finds the function slot for foo because that's the
first symbol, it finds the variable slot for bar because it's not first.
Finally, 'baz returns the symbol itself.  To be more careful: (quote
baz) returns a list containing the symbol, which evaluates to the
symbol.

And use:

   (defun …
    )

instead of:

   (defun …
      …
      (unless (boundp 'my-macro-counter) (setq my-macro-counter 0))
